You spend about 60% of your waking hours at home. Having the cleanest indoor air quality is paramount whether you live in a large city or out in the country. Here are four common indoor air pollutants and what you can do to keep your air clean and healthy.

1. Mold

Mold spores grow on any surface, including shower curtains and walls in homes with high humidity. According to the CDC, they’re present in at least 50% of homes in the U.S.

It thrives in damp environments like kitchens, bathrooms, and basements where there are problems with leaks from dishwashers or condensation from showers or bathtubs.

2. Smoke

Smoke is one of the major indoor air pollutants that can cause health problems. It’s most often caused by tobacco smoke, but it can come from anything that burns, such as wood or kerosene heaters and candles.

Smoke can also be produced by certain types of cooking equipment like gas stoves. Even if you don’t smoke yourself, there’s a chance your home has secondhand smoke exposure if you have one.

3. Household Chemicals


Volatile organic compounds (VOCs) can be found in household products like carpet cleaners, furniture waxes, and spot removers; from aerosol sprays; from personal care products such as hairspray; from glues used in making plywood cabinets or furniture; and even from new carpeting that has been sprayed with fire retardants, and pesticides. These substances can cause various health problems, including headaches, nausea, and irritation for those exposed to them.

4. Pet Dander

Pets shed skin cells and hair continuously. When they do this on a carpeted floor or upholstered furniture, the dander sticks around for days or weeks until it’s vacuumed up.

How to Keep the Air in Your Home Clean

The good news is that there are steps you can take to increase the air quality in your home.

1. Vacuum regularly. Vacuuming pulls up dust, pet dander, and pollen from carpets and rugs, which can reduce the number of contaminants in the air you breathe by as much as 90%.

2. Change your air filters regularly. A dirty filter restricts airflow and makes it harder for your furnace or air conditioner to work effectively.

3. Use a HEPA air purifier in bedrooms at night when sleeping or invest in an air filtration system for the whole house.

HEPA air purifiers remove at least 99.97% of particles such as dust and pollen from the air, making them a good choice for people with respiratory allergies.
